Operations
This chapter describes the hardware operations carried out prior to and after installing or removing a
hardware option, or performing a server maintenance or troubleshooting procedure.
Before performing these hardware operations, review and observe the server warnings and cautions.
Power up the server
The DX chassis firmware initiates an automatic power-up sequence when the servers are installed. If the
default setting is changed, use one of the following methods to power up each server:
• Use a virtual power button selection through iLO 5.
• Press and release the Power On/Standby button.
When the server goes from standby mode to full power mode, the server power LED changes from amber
to green.
Power down the server
Before powering down the server for any upgrade or maintenance procedures, perform a backup of
critical server data and programs.
IMPORTANT:
When the server is in standby mode, auxiliary power is still being provided to the
system.
To power down the server, use one of the following methods:
• Press and release the Power On/Standby button.
This method initiates a controlled shutdown of applications and the OS before the server enters
standby mode.
• Press and hold the Power On/Standby button for more than 4 seconds to force the server to enter
standby mode.
This method forces the server to enter standby mode without properly exiting applications and the OS.
If an application stops responding, you can use this method to force a shutdown.
• Use a virtual power button selection through iLO 5.
This method initiates a controlled remote shutdown of applications and the OS before the server
enters standby mode.
Before proceeding, verify that the server is in standby mode by observing that the system power LED is
amber.
Remove the server from the chassis
CAUTION:
To prevent improper cooling and thermal damage, do not operate the chassis unless all
bays are populated with a component or a blank.
